Research On Electric Vehicle Demonstration Operation Comprehensive Evaluation Method

In recent years, under the energy crisis and environmental protection under double pressures of countries all over the world are strongly in research, development, popularization and application of electric cars. The development and popularization of electric vehicle has become reduce automobile emission pollution and improve the energy structure and to realize the inevitable choice of auto industry and national economic and social sustainable development has the extremely vital significance.In current electric car is still new things, Electric car development not only, and the huge product price is obviously higher than the traditional type, with real application range, except for the performance and ascension preferential policies on purchase of new energy vehicles to improve people's understanding, infrastructure construction is indispensable. Therefore in the conditional cities and regions of promoting new energy vehicles and demonstration is particularly important. In early 2003, wuhan, hubei province, shanxi changzhi city will rely on their own advantages in the application of new energy vehicles and operation. By the end of 2008, and to further strengthen the new energy vehicles, science popularization demonstration formally implement "the ten thousands of new energy vehicles" city of automobile application program. Early 2009, ministry of finance, such as 4 ministries decided in Beijing in 13 cities with new energy conservation work, auto pilot demonstration expansion of pilot city in transit encouraged, business, lease, sanitation and postal etc. To promote the use of public service domain new energy saving and cars.This paper combining technical characteristics, electric car from the technical, economic and social benefit analysis of electric vehicle use efficiency and environmental factors. Follow the systematic, scientific and comparability, measurability and can and social benefits, constructing electric vehicle operation Angle screening effect of comprehensive evaluation index system. Then the electric car running comprehensive effect evaluation indexes for evaluating index method, the methods are consistent with dimensionless. Through multiple fuzzy evaluation model for evaluation index of a comprehensive evaluation value. Finally, using electric vehicle demonstration operation comprehensive evaluation method, taking chongqing hybrid taxi demonstration project operation volunteer xiang hybrid cars comprehensive use efficiency evaluation.
